I didn't read the "Test results" but my racecar used water and water-wetter
only.  In competition situations or on courses you may share with other
vehicles, anti-freeze is a "No-No" because it is very slippery.  If Mike's
son is a 'rock crawler' who tries oft-used terrain challenges, spilling
antifreeze on the routes would be frowned upon.  One fellow forgot and had
some antifreeze mix in his 944 street/race car, spilling some on Portland
Int. raceway during an event...caused lots of mahem.  Expensive  crashes but
nobody died.
  Now on the other side, I forgot to drain my racecar one fall and ruined an
engine...a $20k mistake because it was out of sight sitting in it's
car-hauler trailer...
  I also run water wetter in my big KTM when running in Baja in the deep
sand, it does run much cooler..No science other than my own eyeballs and a
bunch of years trying it both ways with the bikes and the cars.
